K&N High-Flow Air Filter | Porsche Cayenne (955 / 957) 2002-2009 | Sold Each
K&N 33-2857 High-Flow Replacement Air Filter is the drop-in element for the first-generation Cayenne. It fits the standard airbox with no modification and replaces the disposable paper filter permanently.
Oiled cotton, the original high-flow media. K&N layers oiled cotton gauze between epoxy-coated aluminium mesh, rated to flow up to 50% more air than a paper filter and tested in an ISO 5011 laboratory for filtration efficiency. Supplied pre-oiled; washed and re-oiled with a K&N Recharger kit, with up to 50,000 miles between cleanings under normal highway driving. Be sparing with the oil — an over-oiled element is how filter oil ends up on a mass airflow sensor.

Note: K&N lists 33-2857 without a multi-filter annotation — it is supplied as a single filter. K&N's application entry also covers the platform-shared VW Touareg and Land Rover Range Rover; the Porsche coverage is as listed above. Clean and re-oil with a K&N Recharger kit and apply oil sparingly.
Installation Instructions:
On a car that earns its keep, a filter you rinse instead of rebuy pays for itself quickly.
